RFID readers transmit radio frequency (RF) signals through an antenna, which is then received by RAMP-RFID tags that use this energy to power up their embedded chip and return RF signals, which readers capture and decode.
Data collected via sensors is then transmitted to a connected system for processing, allowing companies to monitor inventory and sales levels, for instance, effectively.
Cost-Effective
RAMP-RFID readers are essential to an RFID system, converting radio frequency waves from an RFID transmitter into signals that RFID tags can read. There is a range of sizes and specifications depending on application needs.
As RFID tags pass through a reader, they become active and transmit wireless signals containing their ID information to its antenna. Once there, their control module demodulates it while measuring RSS (received signal strength), allowing it to determine their locations accurately.
Businesses can reduce labour costs by automating data collection and inventory management with RFID readers. For instance, clothing retailers could use fixed RFID readers to scan items brought into store stockrooms and outgoing shipments as soon as they come through to customers – providing real-time visibility into inventory levels while helping reduce shrinkage issues and streamlining stock replenishment operations and sales operations.
Easy to Install
RFID readers (sometimes called interrogators) send signals that activate tags. The tag sends an electromagnetic signal back to the reader, letting it know what data has been stored on its tag and can then be translated and displayed onscreen.
Warehouses can use RFID to reduce labour-intensive processes like inventory tracking and monitoring production lines, reducing lost inventory, better distribution logistics and reduced stock-outs. RFID can also aid healthcare by providing accurate patient analysis and tracking – which helps hospitals minimise errors for improved patient safety.
Versatile
RAMP-RFID readers offer many advantages over barcode scanners in speed and versatility, such as reduced labour and inventory management costs and error rates, increased productivity, reduced error rates and greater productivity. They are ideal for inventory and asset tracking as well as supply chain management, eCommerce sales, manufacturing operations and manufacturing operations – with the latter two using barcodes for identification.
Readers come in various forms to meet the unique requirements of your business. Portable readers can be built into handheld devices for mobile inventory management, enabling workers to scan multiple items without stopping to type results in manually. Fixed readers, however, are best used on production lines as they track the identity of each item while transmitting this data back into a central system.
High Accuracy
RFID technology can assist your organisation in tracking inventory or automating manufacturing processes with cost-effective, reliable solutions that improve productivity and accuracy by eliminating errors. RFID simplifies managing operations while saving time, money and resources – not to mention it can also integrate with asset management software for easy tracking and monitoring processes.
An RFID reader’s antenna can detect backscattered signals from tags and collect their stored information. Once received, the data processing module of the reader demodulates the signal before sending it to a computer for analysis to locate the RFID tag location.
Researchers have developed an algorithm for detecting breathing patterns using RFID readers by monitoring the phase data from RFID reader’s wireless signals. Still, discontinuities can hinder this approach due to channel hopping. To counter this issue, researchers created the “Count attribute”, which aggregates multiple readings of one tag in unit time.
Safety
Some individuals worry that RFID can be misused to gather personal data without their knowledge, creating privacy risks for consumers. Meanwhile, military and medical settings could face life-or-death situations without adequate security features in their RFID systems. As such, security is of utmost importance in any RFID solution.
These systems must be capable of reading both passive and active tags, which differ in how they get their energy; passive tags draw their power from an electromagnetic field created by readers (similar to barcodes), while active tags use batteries to boost signal strength for reading purposes. Furthermore, interference caused by other medical equipment, metallic objects, liquids or glass and humid environments must also be considered.
RFID readers often utilise frequency hopping as a strategy to prevent frequency selective fading and co-channel interference from occurring while simultaneously changing phase values every 0.2 seconds so attackers cannot easily spoof or hijack signals.
